My invention relates to a device for the dustless discharge of dustbins into refuse collecting carts. o

For the dustless discharge of dustbins into refusecollecting carts devices are known in which the lid of the dustbin is coupled with a hood adapted to seal the charge opening of the cart and to swing between side walls so that when the dustbin is tipped into the cart the hood and the lid of the dustbin are opened simultaneously. i

Such devices have the drawback that during the tipping of the dustbin the lid of the bin actuates the hood and carries it along into 'the interior of the cart. In this way the lid of the dustbin is unnecessarily strained and becomes prematurelydestroyed and the cart cannot be charged up to its full capacity owing to the room necessary for the lid in the interior of the cart.

According to my invention a substantial improvement is brought about by forming the hood sealing the charge openlng of the collecting cart of individual plates 101I1Bd t0- 7 gether by hinges, the pivots of which are so located that when tipping the dustbin the plate of the hood coupled with the l d of the bin'describes a line which runs substantially parallel with the roof of the cart, the lid of the dustbin being thus carried forward along the roof of the cart and does not project into ts interior. For relieving the lid vand'perm tting it to swing freely, it is hinged to the bin by means of a hinge pin spaced from the body of the dust pin. This pin simultaneously serves as a coupling member to enable the dustbinto be coupled with an open eyeor jaw member upon the hood and thus with the hood itself, the axis of the hinge pin of the lid being in alignment with the axis of the hood hinge so that the dustbin and; the hood are rigidly connected.

An embodiment of myinvention is illustrated in the accompanying drawing. 7

Fig. 1 is a central longitudinal section through the closed hood of the refuse collecting cart according to my invention, with the dustbin suspended therefrom,

Fig. 2 is a central longitudinal section through the hood withthe dustbin in its tipped condition, and

Fig. 3 is a perspective'view of the hinge of the lid with part of the bin.

Referring to'the drawings, it will-be seen that the hood formed by the plates 2, 3 and 4- is adapted to swing or rock between the side walls 1. The plates 2, 3 and 4: are joined together by hinges 5, 6,7 and 8. The hinge 5 is located at the rear wall 9 while the hinge 8 is attached to the roof 10 of the cart. The front plate 4: of the hood is provided with a recess or opening corresponding with the mouth of the dustbin 17 On the plate 3 is rigidly fixed a plate 11 which in the inoperative position abuts against the front wall 4. The platell is provided at its upper part adjacent to the plate 3 with a depression 19' for a purpose described later on. In alignment with the hinge 7 a forked member or open eye 12 is provided on the plate 3 at its end remote from the hinge 6. The lid 13 of the dustbin 17 is joined to the bin or receptacle by a hinge 14 withfan accessibly disposed or floating pin 15. L The hinge pin 15 is journalled in two separate brackets 15' mounted upon the receptacle 17 and the lid 13 engages the pin 15 by means of two brackets 13'mounted upon it in such a mannerthat between the brackets 13., the pin 15 is freely accessible. 1 The lid of the dustbin is provided with atongue or strip 16 diametrically opposite to its hinge 14 while below this tongue a bolt 18 is mounted upon the receptacle 17. At both sides of the brack= ets 13 stops 20 of angular shape are provided upon the receptacle 17 the free ends of which are located at about the level of the upper edge of the bin 17 At the lower part of the outside of the front plate 4 there is also provided above the hinge 8 a book 18 intended for the reception of the bolt 18 for suspending the bin. j

The manner of operationof my improved device is as follows: F

The dustbin17 to be emptied into the collecting cart has its bolt 18 engaged with'or suspended from the hook;18' and is tipped, around this bolt, the tongue 16 of the lid13 engaging first the recess 11' of the plate '11 through the opening in the front wall 4. .Dur-

ing the further tipping of the dustbin the hinge pin 15 engages the open eye or forked member 12, the lid brackets 13 being located in the recess 19 of the plate 11 while the stops 2O abut against the front wall 4. The clustbin is thus coupled with the hood while the lid is associated with the sealing plate 11. When the receptacle 17 is further tipped into the position shown in Fi 2, the stops 20 press against the plate 4 whlle the bolt 15 actsupon the hinge 7 in such a mannerthat the plates 3 and 2 pass out of the way and together with the hinge 6 move first upwards and then'again downwards in a circle. During this motion a the lid 13 of the dustbin in engagement with the sealing plate 11 is moved forward by the; plate 11 owing to the rigid connection of the latter with the plate 3, the lid 13 opening and its front edge describing a line a approximately parallel with the roof of the cart. Whenthedust bin 17 is withdrawn from the cart, the hood is carried along by the hinge pin 15, the dustbin being closed by the lid 13 and the charge opening in the plate 4 by the plate 11 and the open eye or forked member 12 releasing the hinge pin 15.
